The top incidence is now cardiovascular diseases, followed by malignant tumors, and there is also a rapid increase in the incidence of mental illness. If you simply look at these data, you may not know why we have such a shift in the disease spectrum. But have you ever thought about: the disease comes from the mouth, and Chinese medicine said “people eat the Qi of heaven and earth to be born, internal injury in the seven emotions of joy, anger, sadness, pity, fear and alarm, external injury in the wind, cold, summer, humidity, dryness and fire, so sick.” That is, whether the food we have eaten recently is healthy, whether we have paid attention to the inner cultivation. Food can provide nutrition and at the same time can be refreshing and pleasing to the eye. In addition to providing nutrients, food must also satisfy the needs of the mental level. When you are full, you can’t eat anymore, but when combined with endless cravings, you forget the main purpose of our eating. Providing nutrition is the first level, the primary role. Pleasing the eye is the second level. It is difficult to divorce the two from food. As people become more affluent, they eat too much nutrients, which cause stagnation in the body and become cardiovascular diseases. There are two sides to everything, and food is no exception. It either contains toxins directly, or is metabolized by the body to produce toxins. When you do not eat too much, too much, toxins can be excreted through the body’s detoxification function. But in excess, beyond the scope of the body’s ability to detoxify, it naturally produces malignant tumors and other diseases. We want to be healthy, we must do a few things: First: nutrition is good enough. Second: enjoy a small amount of food, fine taste. Third: pay attention to rest and exercise. Fourth: have culture and faith, to appease the soul emotional needs.
